The experience, gained by this procedure, leads t'o 

 another test,, which turns out well. The tank is used- as a 

 spawning tank, ' Ip'omea is placed in about^ three -fourth of 

 the tank area, This is prepared during the spawning s-eascn. 

 5 males and 10 females are put in. Within a few days, the 

 fish will spawn. . The nests -with eggs are then transferred 

 to : another tank,, while the '-s pawners are 'allowed to remain 

 ;to continue their spawning activity in the previous tank.' 



The fry are fed in the tank w- th water-fleas and cope- 

 pods in the. same manner as mentioned elsewhere. After one 

 ■ month, they 'are'' transferred to the nursery ponds., 



TRi-iNSPORTATION . 



. ■ The transportation -of pla 3alid is also tried. If Is 

 found that small plasalid,,5 centimetres in length, can 

 stand long .^oumety better than large ones. The "fish, after 

 :aken up from the pond, are put in wooden- tanks with' clear 

 and cool water, and-are given' 'one day's rest. --During -.this- 

 time and the journey, no food should be given. The fish, are 

 put in round tin cans, having 20 litres capacity. Three-

 ing to fish sizes: for Instance, for. full grown size l^O, for 

 med^iiim size 80 and for 'small size, 5 centimetres In length, 

 200, During the journey, the cans should be covered with 

 perforated' lids and placed, if' possible , in aool or damp 

 places. The water should be f requently-a-^HTO.ted,.with the use 

 of a perforated' dipper. ; How.e-ver-y;-food result is obtained by 

 changing water -every 4 hours.
